Described in general tcrmshvthe machine comprises two totalizers; actiiating mechanism therefor, controlled by group-s of depressible keys: an indicating mechanism selected by said keys commensurate with lhe value of the key which is operated; a printing mechanism for printing a detail strip; four special transaction keys, each having associated therewith a special counter to count the number ot' ac tuations of their respective keys; and-'a clerlsinitial key.

Key-board.

Described in detail, the key-board comprises four transaction key levers 25; one clerks initial'lev'er 26 g' one 5 lcent key Vlever 27; nine amount key levers 28 arranged from 10 cents to 90 cents; and tive key levers 29 arranged from $1 t0 $5.

The transaction key levers 25 are Cash, Charge, Received-omaccount and Paid out.

IThe key levers 25 to 29, inclusive, are all loosely mounted on a rod 30 (Figs. 6 and 11)',- carried by parallel side frames 81 and 32 (FigsflA, 1B, 2A and 21.3).

The rear end ot each of the levers 25, 27, 28 and 29, rests`on a bar 38, mounted between the iranes 31 and 32.

Secured to the bar 33 and to another bar 34` (Figs. 6 and 11) is a plate 85 having slots l (not'shown) thereim'which are for the purpose ofkeeping the rear end of the'levers in their proper lateral positions.

The forward end of the levers are held in their lateral positions'byimeans of slots (not shown) formedf in a plate 36 (Figs. 6 and 11)- and mounted between a rod 37 and a bar 38, both of which are carried by the side frames l31 and 32.

The l'keyr levers 25, 28 and 29 are arranged in groups and by ifne'ansto be hereinafter described, it is impossible to operate more than one key in any onegroup' atfthe same time".` However, any key'ofeach of two'or more grupslmay be 'simultaneously operated.

The means fer preventing the depression ef more thenehe -ker in ein' 011e greep et one time comprises a pluralityY of arms 45 (Fge- 2'* end 2B) riveted et 4 6 between the ber '33 en e' plete 47, Secured fethe 'Said bar. These arms (ro-operate with extensions 48 on the levers 25, 27, 28 29,. There are three arms 4.5 fle-Operating with the levers'25;4 eig'htarms 45 co-operating withv the'le'vere, 28;'a1'1d feel" arme 45 .ee-Operating with the levers 29. 'The proj ections 4801il the rear of these levers extend`,'as viewed. in Figs. 2A and 2B, between the arms 45 so that when a key in e certain group ie. depressed 01. rocked ceunter-cleckwee (Figs 6 'and 1,1.) the Pfeieeten 48 thereen ,Spreads the en?! 45 on either side thereof apart, thereby' mov-V ing all of the arms 45 associated with that group of and locking them so that it is impossible' tio; depress another key in the same group.

The'rear end of the clerks lever 26 (Figs. 6 19 and 22) is not like the rear end of the other levers and doe-3 not extend backward to the bar 38, but has integral therewith an arm 49 carrying a pin 50, which co-operates with an arm 51 pivoted at 52 to an L-shaped bracket 53 (Fig. 3), carried by a key coupler 54, fast on .a shaft 55, carried by the side frames 31 and 32.

The arm 51 is provided with two projections 56 and 57. The projection 5,6 co-op'erates Witha stud 58 carried by lever 59', loose on the rod 30. The projection 57 cooperates with a stud 60 carried by a lever 61 loose on the rod 30. These levers 59 and 61 are for the purpose of selecting the clerks initial indicator and rocking the proper clerks totalizer into engagement with the actuators to be hereinafter described. These levers are provided with extensions 48 (Fig. 2A) and co-operating with a. single arm 45, thereby preventing the operation of both levers during one operation of the machine. The lever 26' (Fig. 1B), which extends forward, carries the inscription B,`which designates clerk B. lfVhen this lever is operated or rocked clockwise" (Fig. 22)

around the rod 30, its integral arm 49, through the pin 50, rocks the 'arm 51 clockwise, thereby moving the projection`56 underneath the stud 58`vcarried by the lever 59. lVith the projection 56 in this position, when the arm 51 is raised by means to be hereinafter described, Bs totalier'is rockedinto engagement with-'the'actuators and Bs indicator is selected and exposed to view.

However, whenv the varm 51 is cansed to remain in thel position shown in Figs. 6, 18 and 22, upward movement of 'the 'arm 51 through the pin 69 and theprojection 57, rocks the lever`6l clockwise (F 18)', and thereby, through means to be hereinafte described, causes As totalizer t'o be rocked into engagement with the actuators 'andalso canses As indicator to he selected'and exposedto view. 2 i

When clerk B is operating the machine, there' is means provided wherebyl when the B key 26`is depressed, it will remain depressed until an amount key lhas been operated, after which said B key'returns to its normal position. This means is a portion 62 (Figs. 8, 6, 19 and`22) bent out-'from the side ot' the arm 49 so that it lies in the'plane of a hook 63 integral with the lower end of a lever 64, loose on the' shaft 55. Theho'ok 63 is held in the position shown in Figs. 6 and 22 by a. coil spring 65 stretched between the lever 64 and a lpin carried by the arm 51. incidentally, this spring 65 also serves'to maintain'the arm 51 in its normal position. Then the lever 26 is depressed it rocks the arm 49 counter-clockwise. 6) and clockwise (Fig. 22) andf'p'ositioiis the projection 56`underneath the pin 58, as previously described.` The lportion 62 israised whereby the lever 64 is rocked clockwise under the influence of the spring 65, so that the ltlO and rocks it counter-clockwise which disengages its hook 63 from the portion 62. A spring 67 then returns the lever 26 to normal position.

As before stated, the key coupler 54 cooperateswith the key levers 25, 27, 28 and 29 and also with `the two levers 59 and 61. As iswell known in'the art, the purpose of the keyicoupler is to permit the starting of an operation of two or more keys, for example, the $1' key and the 60 key, and then complete the operation'by pressing 'either one o the keys'. This ,is'accomplished through a lip 7 )Vengagin'g notches 71 in the keys 27 and 28,/ and'29. ,The 1ip'70 on the key- ,coupler normally'glies againstthe upper ledgeof the rear portion of the keylevers 27, `28and 29, and also the'leversz59.A and 61andis held there its ownv'fei'ght. Depression of a key 27, 28 or 29 causes said ke t'o rock counter-clockwise 6 and 11 ,whereby the lip 70 engagesthe notch 7 1 and the key coupler is rocked in a counter-cloel'rwise direction (Figs. '6 and '1-1) Aand clockwise (Figs. 18 and 22). All of the keys which are notdepressed are held in their normal position because the lip 7() on the key coupler in its upward 'movement passes just in front of a curved portion 69 on all of the keys which are not operated. When a key has been fully depressed andthe operator releases it the weight of the kep coupler 54 rocks the operated key clockwise to normal position.

- Transaction keys.

The transaction key levers 25 are what are commonly called inv the vart flexible keys, that is, they are so constructed that they may be partially depressed and locked in this position without affecting the key coupler, after which, by depression of any of the amount keys they are carried down the full extent, whereby they will, through means to be hereinafter described, set up the proper printing wheels and proper indicators. These levers are cut away to the line 72 (Figs. 6, 18, 19 and 22) and have pivotally lmounted on the side thereof two .pawls 7 3 and 74. The pawl 73 is loose and hangs in the position as shown by its own weight. The pawl 74 is held in t-he position shown by a spring 79. The lower end rests against a lug, 75 integral with the collar 76, fast on a rod 77, carried by the side frames 31 and :32. Upon depression of the Paid out" keiv lever the rearend of the lever BEST AVAILABLE coe*x is raised whereby the pawl 74 is rocked in a counter-clockwise direction (Fig.l 6) and clockwise (Figs. 18 and 22) by the spring 79 so that the upper end of the pawl strikes the upper end of the pawl 73. This operation of the Paid out key raises the'lever high enough so that the edge 78 is on top ofthe lug 75, thereby retaining the key in its partially depressed position. After lthis has taken place upon the 'depression of any of the amount keys the,key'coupler 54 raises the lever 25: still further and disengages the pawl 74 entiiely from the lug 75, thereby allowing the vspring 79 to rock the pawl 74 still further j Ain thel direction ,mentione d, whereby itsfupper end. hooks ov'er 'the v4point 8O` of the pawl 73, thus locking the'pa'w'ljin a position 'so'that its edge 81' 'orins'fthe bot; tom of a slot' exactly. like theslotj7 1fi1'1`tle other keys; whereby :uren fthe: "Qmpllff de- Prss'ion.- of: y'; fffthe nonilt ekeys' th fFaid out 'key'isfj'carridv with it-` its rear end caused to'be'rafised "ths'ameeirtent as the amount key. VVhenthe opertor"'r`e' leases the key, the key ,coupler '54, itlirongn its engagement with the 'edge'81 'of the pawl 73 rocks the lever 25 to normal position. Just .before said lever 'reaches' lits normal position, the lower end ofthe pawl 74len`- gages the lug 7 5, thereby rockingl said pawl in a clockwise` direction (Fig.'f6)'and coun'- ter-clockwise (Figs. 18 and 22), whereby its hook isfreleased from the point 8O ofthe pawl' 73 and the lever is returned toits normal position.

Actuavng mechamlsm.

There are three groups of actuating devices in this machine for controlling the previously mentioned totalizersand amount indicators; one assoeiatedwith the le'ver27; one device associated with fthe zgroup of levers 28; and another device associated with the group of levers 29. These actuating des vices are controlled directly' by the operation of the amount keylevers 27, 28 and 29. There are also two other actuating devices, one associated with levers 25 and the other with lever 26, for setting the type wheels and selecting the indicators thereby printing and indicating the class of transacion and the clerk making such transaction respectively.

The actuating mechanism associated with the transaction key levers `25 will be described irst. The rear end of each of these levers is provided with a slot 86` (zo-operating with a rod S7 (Figs. 25, 6, 18, 19 a'nd 22), carried by parallel arms 88, connected by a sleeve 89, loose on a rod '90, carried .by the side frames 31 and 32.

Only one of the slots 86 is shown in Fig. 6; Figs. 18 and 22 show how these slots are staggered or arranged at different angles so that when the rear end of the lever is raised, each of the levers 25 will more the rod 87 a different d istance towards the back of the machine. Integral with 4the left hand arm 88, as viewed in Fig. 2^, is a segment 91, meshing with the gear 92, which is for the purpose of imparting movement to the transactien printing mechanism to be hereinafter described. i

"The arm 88, which has integral therewith the segment 91, is provided with an opening 9 5 (Fig. 5) into which projects a roller 96 (Figs. 2A and 6) carried by one end of a link 97, the other end of which is loose on a rod 98, carried by an arm 99 (Figs. 1A, 2B, 9 and 11) and an arm 100 (Figs. 1B, 2A and 6), both of which are fast on the shaft 5,5,"to which is also fast the key coupler 54. Iioose on the rod is a plate 105 (Figs. 2^ and 6) with an opening 106 exactly like the opening 'in the arm 88, and into which projects the roller 96 (Figs. 2A and 6) This plate and roller 96 are for the purpose of d iierentially positioning the indicator carrying mechanism as will be hereinafter described.

(3o-operating with all of the levers 25 is a b ail 107 (Figs. 2A and 6) integral with an arm 108 (Figs. 2A and 6), loose on the vshaft 55. The arm 108 is provided with a projection 109 extending into a notch- 110 in an arm 111,integral with the arm 88, which has the slot 95.

The bail 107 is held in contact with the upper edge of the levers 25h-y coil spring 11.2, stretched between said bail and a collar 113 on the shaft 30.

The operation of the just described device is as follows :-Depression of any one of the key levers 25 rocks said lever counter-clockwise (Fig. 6) thereby raising its rear end and simultaneously raising the bail 107, thus removingr its portion 109 from the slot 110 in the arm 111. J ust before the portion 109 goes out ot the slot the slot 86 in the operated lever engages the rod 87. Said slot is provided with a neutral portion at the top so'that as the lever is moved still further the rod 87 is not moved out of position until after the portion 109 is entirely disengaged from the slot 110 in the arm 111. After this happens the angular portion of the slot 86 moves the rod 87 towards thc rear of the machine, thereby rocking the arms 88 and consequently the segment 91 in a counterclockwisel direction, thereby rotating the gear 92 clockwise a dist-ance corresponding to the angle of the slot 86 in the operated cey.

' Vhen the key coupler 54 is rocked counterclockwise (Fig. 6), (which rocking it will be remembered takes place after the depression of one of the amount keys 28 or 29, it being impossible to fully depress one of the levers 25 without depressing vone of the amount keys), it rocks t-he shaft 55 and consequently the arms 99 and 100 in the same direction,

lleeee thereby moving the link 97 towards the front of the machine. 1This forward nievement of the link 97 takes place approximately at the saine time that'the ar1n`88 is being rocked in'afcounter-clockwise direction under the control of the slot Let itbe 'assumed @het before the Opere.- tion just described 'that the were in the position illustrated in Figs. f5 '6 l As tlie'arm' 8 8 is rncked counter-clockwise and the link 97 is being movedtoward the front of the machine, the roller 96 will follow the edge 93 of the opening 95 in the arm 88 until it comesto a nentral portion 114 or the portion 101 (Fig. of said open- Due to the ffet'that the Peeitien of the opening 95 is changed from that ofthe opening 10e in the' armlo, are relier 9 6 (because it projects into both ope ings and v10e) will. follow'tlle 'edge 102 0f. the opening 106 in the plate105'and move the plate 105 eeuliterlelcl'fwiee 'metil the feller 96 comes to a neutral portion ll'orthe portion 10.4. in Sfed Opening the 'relier is in the portion 101' (Fig. 5) 'the portion 104 (Fig. o r the neutral portions'114 and, 115. it has Positioned the plete, 1,05 e611#- inensurate with the aigle Q the slot 8,6 (Fig. 18) of the key which has, been. operaie-e1.:

vWhen the arm 100, is in its extreme moved position, 'a radiusstrlick' frfoni tlie'eenter of rod 98 and passing througlithe center of roller 96 would intersect a ra'dius struck from the center of rod 90 :ind passing through the radius point of the portions.101 and 104 of the arm 88 and plate 105. These two intersecting points are the extreme upper and lower differential positions of the arm 88 and plate 105. .To insure the proper setting of the plate 1 05 at all differenti'al positiens between said points the neutral portions 114 and 115 are provided. Said neutral portions are equal in length ioo to the sum of the height of the two segments of the intersecting arcs.

The clockwise movement o f the key coupler 54 (Fig. 6) to normal position roeks the shaft 55 and the arms 99'and 100 likewise thereby moving the link 97 towards the rear of the machine. In its rearward movementthe roller 96 on the link 97 has no ei'ect upon the plate 105, because, for reasons to be explained in connection with the indicating mechanism, this plate is :illowed to remain in the position into which it has been set. until a subsequent operation of the machine.

J ust before the operated .key reaches its home position the portion 109 of the arm 108 engages the slot 110 in the arm 111 and holds said arm, the arm 88, the. segment 91 and the rod 8T in their normal position.

If an operation of the machine involving the Paid out key is made, the plate 105 (Fig. 6) is rocked Counter-clockwise to its farthest position and caused to remain in this position by means to be hereinafter described until a subsequent operation ot the machine.

Should the subsequent operation of the machine involve the operation of a Cash key, when the link 97 is moved towards the front of the machine its roller 96 follows the edge 93 of the opening 95 in t-he arm 88 until it reaches the neutral portion 114 of said opening. During this operation the roller96 engages the edge 103 of the opening 106 in the plate 105 and rocks the plate in a clockwise directfon until the roller is engaged in the neutra-l portion 115 of said opening 106. This positions the plate 105 from the Paid out position in which it was left in the previous operation to the Cash position in the subsequent operation.

The differential mechanism associated with the clerks key 26 and the clerks levers 59 and 61 is shown only in Fig. 2^, but as this mechanism is substantially the same as that described in connection with the transaction keys only a brief description of it will be given.

The levers 59 and.61 are provided with slots similar to the slots 86 in the keys 25 and co-operate with the stud 120 (Fig. 19) carried by an arm 121 loose on the rod 90.

Integral with the armv 121 is a segment 122 meshing with a gear123, which is for the purpose ofsetting up the clerks initial type wheels, as will be hereinafter described. Also integral with the arm 121 is another arm (not shown) like the arm 111, shown in Fig. 6. This arm is also provided with a slot like the slot 110 and has co-operating therewith, an aligning4 arm 124 (Fig. 2A) having integral therewitha bail 125 (Fig.

18), extending-across 'the top'ofl the two levers 59 and .61 andheld in this position by a spring like thespring. 112. 4Also loose on the rod 90 and adjacent the arm 121, is a plate 126, identically like. the plate 10.5 associated with i the 4transaction keys.

Loose on the rod. 98 is a link 127 carrying the roller 128, which extends through'openings (not shown) in the arm 121 and plate 126. The openings are identically the same as the openings in the arms 88 and plate 105 respectively. i

The operation of this differential mechanism is exactly the same as that used in connection with the transaction keys, lonlythat instead of having four key levers controlling the movement of the arm 121, there .are only twol levers 59l and 61.`

The 5 cent key lever 27 has associated therewith a differential mechanism which is identically the sam-e as that just described in connection with the clerks levers 59 andl. j

The lever 27 is provideduwith a slot 129 (Fig. 6) which tro-operates with i stud 130 aesT AVAILABLE com s (Fig. 2^) carried by an arm 131 like the arm 88, loose on the rod 90. The arm 131 also has integral therewith a segment 132, meshing with a gear 133, which is for the purpose of setting up the 5 cent or units type wheel, to be hereinafter described.

This arm 131 also has co-operating therewith an aligning arm 134, loose on the shaft 55. Integral with the arm 134 is a bail 135, which .extends over the top of the 5 cent lever 27, and is held in such position by a spring 139 (Fig. 18) like the spring 112, previously described. Also loose on the rod 90 and adjacent the larm 1.31 is a plate 136, like the plate 105.4 The arm 131 and plate 136 are provided with openings like the openings 95 and 106 respectively, in the arm 88 and plate 105.

Loose on the rod 98 is a link 137, carrying a roller 138, which extends through the openings in the arm 131 and plate 136, and is for the purpose ot selecting the indicators, to be hereinafter described, asociated with the 5 cent key lever 27.

The operation of the differential mechanism associated with the 5 cent lever 27 is practically the same as that associated with the transaction key levers 25, therefore, this operation will not he repeated here.

The differential mechanism associated with levers 28 will now be described -The levers 28 are each provided with a slot 145 (Fig. 11) set at different angles and cooperate with a rod 146 (Figs. 2A, 2Bv and 11) carried by parallel arms 147, secured to a sleeve 148, loose on the rod 90. Integral with the arm 147 (Fig. 2B) is an arm 149 (Fig. 11) having a slotl 150 into which projects a portion 151 of an aligning arm 152 loose on the shaft 55. Integral with the arm 152 is a bail 153'which has integral therewith another arm 154 (Figj2A) loose on the shaft 55. The bail 153 extends across the top of all of the levers 28 and is heldin contact therewith by a coil spring 155, having one end secured to a projection on the bail and the other end secured to a collar 156 on the rod 30.

Fast on the sleeve 148 is an arm 157 (Figs. 2B and 11) having pivotnlly mounted there-on at point 158 a bell crank 159. This bellcrank co-operates with a transfer mechanism to be hereinafter described. crank 159 carries an antifriction roller 160 projecting into a slot- 161 formed in an arml 162, mounted loosely on the sleeve 148. The roller 160 is held in the bottom of the slot 161 by the coil spring 163, one end of which is secured to the stud uponwhich the rolle-r 160 is mounted, the 'other' end being secured to 'a pin carried by the arm 162.- Integral withthe arm 162 is a segment 164 (Figs. 1A, 2B and 11)., meshing with a gear 165, which is for the 'uipose of actuating the 108 totnliei eel and also for setting lill) up lthe type wheel, as will be hereinafter described. A

Also secur'ed to the sleeve 148 is a `plate 169 (Figs. 2B, 10 and 11) provided with an opening 170, into which extends` an antifriction roller 171, carried by 'a link 172, the other end of which is vpivoted on the rod 98. Lo'ose on thesleeve 148is a plate 173, provided 'Wi'th an opening 174 exactly like the opening 170. These openings are identical with the openings 9'5 and 106 previously described. This plate is for the purpose lof selecting th'e 'indicator commensurate with the value of the key depressed, 'as will be hereinafter described.

The .operation of the. just -described mechanism is as follows: Up'on depression of', for instance, the 60 key lever 28, said leverijs'rocked counter-clockwise (Fig. 11), thereby raising the b'ail 153, and rocking the arm 152 cunter-clck\'vise, 4and disengaging its portionll from thearm 149. Just before this disengagement, the slot 145 .'en-

' gages the r'od 1`46 and rocks 'the arm 147 the -sleeve, 148 and the arm 157 in a counterc'lockwlise direction a distance depending up'n the 'angle oit the slo't 145.v The counter'- clockwise movementof the arm 157 'causes the arm 162, and consequently the segment 164, to be rrocked counter-clockwise through the bell crank 159, roller 160 and slot 161, thereby rotating the gear 165 in a clockwise direction 'a distance'commensurate with the value of the key depressed.

` to its normal position.

The counter-clockwise movementof the lever 28 also rocks th'e key coupler 54 and the shaft 55 counter-clockwise thereby rocking the arms 99 and 100 counter-clockwise, and causingthe ro'd 98 to be 'moved towards the front. of the machine, thereby moving the link 172 therewith. The plate 169, being fast to the sleeve 148, is consequently rocked counter-clockwise simultaneously with the movement ofthe arm 147 and'arm 1'57. The forward movement of 'the link .172 takes' place at the same time the plate 169 is boing rocked counter-clockwise. and as the roller 171 projects through the slot 17 0. in the plate 169 and also the opening .174 in the plate 173, the latter is also rocked counter-clockwise about the shaft a distance dependent upon the movement of plate 169. 'lhe variable movement of plate 173 is used to sclect the indicator by means to be described.

ll/'hen the lever 28 has been fully dcpressed, the operator releases said lever, and through the-weight of the key coupler 54 the lever is rocked in a clockwise 'direction This movement, through the slot 145, rocks the arm 147, sleeve 148, arm 157 and the plate 169 in a clockwise direction to their normal position. Through the bell crank 159, the arm 162 and segment 164 are rocked clockwise to their normal position. It might be stated here that in i"ig. 11 the segment 164 and bell. -crank 159 are shown in a positionmin which a transfer has taken place, consequent-ly the segment 164 is moved one step further towards the right than it would normally be. In the normal position the rollerv 160 is in the upper part Aof the s10t161.

The means for stopping the segment 164 in the normal position so that no .transfer will take place will be hereinafter described in connection with the transfer and totalizing mechanism. l A ,A n The clockwiseniovement ofthe key coupler 54 to normal position ,rocks the shaft 55 and -the arms I99 and 10() in 4a clockwise direction, .thereby moving the link` 172'towards the rearhof the machine, but in this rearward movement, .the roller 171lras no ettect upon theplate 173 bekcausegforyreasolis to be hereinafter described,A theplate 173 is not returned 4to its normal position, but allowed to ,remain in the poasltio'n. 'in which it has been set, until a ,subsequent operation of the machine, in order U spring 155, is caused to engage the notch 150 and arm 149, thereby alrgni'ngtlie ari'n 149, the arms 147, rod 146, the arm1`157 and the plate 169 in `their normal position.

The differential mechanism associated with the dollar key levers isfsilbstantially the same as that 'describedin connection with levers 28, therefore, but a brief-descrip*- tion will rbe given here. f

Each ot the levers 29 is provided with 'a slot 179 (Figi. 11) which [co-'operates with a rod 180 (Fig. 2B) carried by parallel arms 181, fast ,on la sleev 182, mounted on the rod 90. Integral wi ithfe left handarin 181 is an arm 183 like tie arm 157. This arm 183 carries a bell crank 184, carrying .an anti-friction roller 185 projecting into a slot (not shown) in an arm 18.6, loosely mounted on thcsleeve 182. The bell crank 184 and roller 185 are identically the same as the bcll crank 4159 and roller 160 associated with the levers 28.

integral with the arm 13.6 is a segment 187. n'icshing .with u gear 188. The arm 186 and segment 187 are identically the same as the arin 162 and segment ,164previously de scribed. The gear 188 is for. the. purpose ol actuating the units of dollarsf totalizer wheel and also for setting up thetype wheel associated with that amount. Integral with the right hand arm '181 (Fig. 2B) is an arm identically the same as the arm 149 and carries a slot like the slot 150, with which co-` operates an aligning arm 189 loose on the shaft 55. Integral with the arm 189 is a bail 190 extending across all of the levers 29. Also integral with the bail 190 is anico iii

` like the spring other armv 191, loose on the shaft 55 and is for. the purpose of giving a bearing to this endofthe bail so that it may be oscillated freely."l The bail 190 is held in contact with the levers 29 by a spring (not shown) but. 155. Also secured to the sleeve 182 is a plate 192, identical with the plate, 169,' having a slot of the same formation into'j which projects an anti-friction' roller 193, carried by a link 194, identical with the` link 172, the other end of the link "i springf197 stretched between a pin 198 car- 194being pivoted to the rod 98.

Adjacent'the plate 192 and loose on the sleeve 182 is a plate 195 identical with the plate 173 and having aslot of the same for- 'mationinto which also projects the roller The operation of the above described devices is identically the same as that given in connection with the actuating mechanism associated with the key levers 28, therefore, it is not thoughtpnecessary to repeat the same description.

- Full stroke, device.

The machine is provided with a fullstroke device so that once an amount rey has been'started its-operation must be completed.

iziThis mechanism comprises a pa-Wl 196 (Figs. 1B.- and 6)V loose on the rod 311; a

ried -by-:the pawl and a '-stud 199 mounted on the `side5frame.31;;an d a'seriesor'l notches 204 formed in'the.upper edge ofthe arm 100. .Counter-clockwise movement of the arm 100icauses said arm to 'strike a point 210 on the pawl l196 and'rock said pawl clockwise. Thisfpoint then'co-operateswith the notches 2041wl'1ereby--the' pawl 196 is maintained in sucha? position that la clockwise movement of the 100-is prevented.

#Atjthe completion of the ,counter-clockwise :movement ofthe armf100 thepawl 196 sidisengaged from-.the 4notches 204 and when the arm 100 is rocked clockwise to normal positionitjgengages a point 211`onthe pawl 19.6,- and:nocks.. said pawl counter-clockwise wherebythe -point 211 coi-operates with the notches-.204 1n such .a way that counterclockwise lnovement of the arm 100 is inipossible...`I i.

. F roin the aboveit can be seen that when the-operator depresses the key he must complete the depression thereof and whenhe releases thc key, after the complete depres- 1 sion, said key must return to its normal position before it or any other key can be operated.

Totalz'zers.

As before stated, the machine. is provided with two totalizers, one for each ot' the two clerks, andifor convenience in description. one of the totalizers will be called Aas As totalizer and the other as Bs totalizer.

The totalizers are supported by a frame BEST AVAILABLE cor-ni ,7

work comprised of two parallel plates 200 (Figs. 1^, 1B, 6 and 11), having one end mounted on the Arod 90 and the otherend supported by a shaft 201 mounted in the Side frames 31 and 32.,

As totalizer will be given a general number 202 and Bs totalizer 203 (Figs. 4 and 11). As totalizer 202 is provided with six totalizer wheels 205 (Figs. 1A, 4, 1l and the units and tens of cents and units of dollars wheels each having Secured to the side thereof, a pinion 206. These wheels are loose on a rod 207, carried by parallel arms 208, fast on a shaft. 209, mounted in the plates 200.

"Bs totalizer is provided with six total- Jzer wheels 215, the units and tens of cents and units of dollars wheels' each having secured to the side thereof, a pinion 216 (Figs. 1A, 4, 7, 9 and 11). These Wheels are loose on a rod 217, carried by parallel arms 218` fast on a shaft 219, carried'by the plates 200.

The pinions 206 and 216 are normally out of engagement with their actuating gears. The pinions 206 and 216, which are secured to the units wheels 205 and 215, are arranged to' be enga-ged by means to be hereinafter described, wit-h a `ucar 220, secured to a sleeve 221,-eonnectcd by a. mortice and tenon connection to a sleeve 222, the other end of which is secured to the previously described gear 1323, which is positioned by the movement of the 5 cent key lever 27. These sleeves 221 and 222 are loose on a sleeve 223, which, in turn,'is mounted on a sleeve 224, loose on the shaft 201. The-purpose of the sleeves 223 and 224 Will be hereinafter described.-

The `pinions206and` 216, which are secured to the 10s totalizer wheels 205 and 215, respectively, are arranged to engage with v`the previously described gear 165 (Figs. 1A, 2B and 7). This gear 165'is se'- cur'cd at 'one end to the above mentioned sleeve 223', and from the previous description it will be rememberedthat this geariis positioned by'th'e segment 164 (Figill) contrclled by thc 10 to 90 key Vlevers 28,'1'

The pinions 206 and 216, which are fast to the units of dollars7 totalizer wheels 205 and 215, respectively, are arranged to be engaged 'with the previously described gear 188. This gear is fast on one end 'of the above mentioned sleeve 224, and is positioned by the segment187 (Figs. 1^ and 2B) under the control of the $1 to $5 key levers 29.

Totalz'eer engaging mechanism. I

234 counter-clockwise (Fig. 4)

chine. rAs there is only one clerks initial lever 26 extending 'out of the front ol the machine, clerk As lever 61 is automatically operated, aswill be remembered, by the pin and arm 51 when the key coupler 54 is raised by depression of one ofthe amount. keys. When this lever 61 is operated, clerk As totalizer 202 is rocked into engagement with its actuating gears. When clerk B operates the machine, he first depresses the'lever 26, as previously described, thereby breaking the connection between the arm. 51 and the pin 60 on As lever 61 and effectively connects the arm 51 with the stud 58, carried by Bs lever 59, so that when the arm 51 is raised by the upward move ment of thetkey coupler 54` ,Bs totalizer 203 is rocked into engagement with its actuating gears.

In the accomplishment of these results, Bs lever 59 isprovided with a pin 230 (Figs. 1B, 6 and 22), which projects into an opening 231 in a .link 232, the upper end of which isUpivoted-toa lever 234 (Figs. 1B, 24,4, 6 and 22)., loose on the sleeve 222. The lever 234 is provided with a cam slot 235, into which projects an anti-friction roller 236, carried by an arm 237, fast on the shaft 219. f

It will be remembered that the arms218 which carry .the rod 217 supporting the to talizer wheels 215 are also fast on the shaft 219. From this and the above description it will be seen that as the lever 59 is rocked counter-clockwise (Fig. 6) or clockwise (Fig. 22) by the arm 51 and stud 58, and as said lever .59 nears the completion of its counter-clockwise movement (Fig. 6) or clockwise movement (Fig. 22) the pin 230 strikes a 'shoulder 238 in the opening 231. lVhen this occurs and by the continued movement of the lever 59 to its full extent, the link 232 is moved forward in the direction of its length, thereby rocking the lever or clockwise (Fig. 22) and through the slot 235 and roller 236 rocks the arm 237, shaft 219 and arms 218 countereelockwise (Fig. 4) or clockwise (Fig. 20), thereby engaging the pinions 216 with the gears 165, 188 and 220. This engagement occurs just before the amount levers 28 and 29 reach the end of their first oscillatory. movement, which is counterclockwise (Fig. 11). The slots 145 in these levers have at their lower ends a neutral portion whereby the rods 146 and 180 are held stationary. This neutral portion is for the purpose of maintaining the gears 165, 188 and 220 in the position to which they have been differentially set until after the totalizer pinions 215 have been engaged therewith, 'as just described.

lith the totalizer pinions in engagement with the above mentioned gears, it can be rocked clockwise to their normal posit-ion by the key coupler 54, the amount according to the value of the key which has been depressed is accumulated upon the units and tens of cents and units of dollars totalizer wheels 215, This is caused, as will be re membered, by the segments 132, 164and 187, in the manner previously described.

When clerk A is registering a sale on the machine, As lever 61 (Fig. 6) is automatically rocked counter-clockwise (Fig. 6) or clockwise (Fig. 18,) and clockwise (Fig. or counter-clockwise (Fig. 18) to normal position, as previouslyA described.

As lever 61 carries a pin 242 (Figs. 1B, 18 and 19) which' projects within an opening 241 like the opening 2 3l, tor med in a link 243 (Figs.' 1B, 4, 18 and 19,), fthe-upper. end of'vvhich is -pivoted to a lever 244,10se on the sleeve 222. -1 f i The lever 244 is provided lwith a cam slot 245, into which 4project-s an anti-friction roller 246, carriedby any arm' 247, fast on the shaft 209.

As previously described, the-arms 208 which carry the rod '207, -Supporting the totalizer wheels 205,' are also fast on the shaft 209. v From this and the above description, it will be clear that when-"AsJ lever 6l is rocked counter-clockwise (Fig. 6) or clockwise (Fig. 18) and when the pin 242 therein strikes the shoulder '248 in the slotl of the link 244 (said Shoulder vbeing identical with the shoulder 238 previously described), the link 244is moved forward in the direction of its length, thereby'rock'- ing the lever 244 counter-cloekwise (Fig. 4) or clockwise (Fig. 1,8) and through the slot 245 and roller 246 rocks the arm `247, shaft 209 and the arms 208 clockwise (Fig. 4) or counter-clockwise (Fig. 20), thereby engaging the pinions 206 with the gears 165, 188 and 220.

This engagement takes place at identically the same time during the operation of the machines as does Bs totalizer pinions 216, above described, and when the operator releases the amount keys and they are returned to their normal position, the amount is accumulated in As totalizer in identically the saine manner and by identically the same means as that described in connection with Bs totalizer; therefore, it is not thought necessary to describe this accumulating mechanism again.

The levers 234 and 244are each provided with two notches 25,0 and 251. Normally engaging the notch 250 in each of the levers is a pawl 252. The pawls are held in engagement with the notches 250 by coil springs 253 (Figs. 2^ and 6) stretched between a pin carried by each of the pawls and a pin 254, carried by the plate 200.

Then either of the levers 234 or 244 is rocked counter-clockwise (Fig. 4) or clockwise (Figs. 18 and 22) upon the'movement of the links 232 and 243, respectively, the pawl is cammed out of the notch 2504 and caused to' engage the lnotch 251, kthus holding thelevers in alignment and consequently holding' the totalizerpinio'ns 206 in their actuating gears. I

When in the position shown in Figs-4, 18 and 22 with the pa-wl in the notch250, said pawl serves to retain the :totalizer pinions 206 and 216 'out of engagement with the actuating gears. v When the. totalizers are outof 'engage-mentgwith the 4act 1 1atin'g gears, thecpinions 206 Iand'216 are held in alignment by spring pressed pa'wls 255 (Fig. 11) which ,engage said pi,n ion s., Then the totalizers are, rocked into` engagement 'the pawls 255 Contact with rods 256, carried by the plates-200, thus allowing the pinions 206 and 216 to be rotated. By referring to Fig. 11, it will be noticed that there is a clearance between the lrods 256 and the pawls 255, which is to allow the pinions to become engaged with the actuating gears before,v the aligning pawls areentirely out of engagement with the pinions,thus insuring that no movement of the totalizer wheels takes place at the time they arefbeing engaged. y

Before the totalizer. wheels are finally Adisengaged from the actuating gears, the aligning pawls 255 are in suchV position that no possible rotation of the totalizer wheels 205 and 215 can take place, thereby insuring a perfect alignment of the said totalizer wheels rat all times.

Disabling device for totalizer engaging mechanism.

For certain operations ofthe machine which do not involve money being. received, it is necessary to hold As totalizer 202 and also Bs totalizer 203 out of engagenient with the actuating gears during the entire operation of the machine. In the present instances, these operations are Charge and Paid out operations.

To accomplish the above, a lever 260 (Figs. 1B, 2^, 6 and 18 and 22) is loosely mounted upon the shaft 55. The forward end of this lever carries a pin 261, which projects into a slot 262 in each of the links 232 and 243. The rear`end of the lever 260 is provided with a slot 263 surrounding the rod 87 controlled bythe transaction key levers 25.

As before stated, the slot 86 in these levers are cut at different angles (Figs. 18 and the Ciisli'key being first, Charge second, Received on account third, and Paid out fourth. The slot in the Cash lever has the eEsTAvAlLAsLE com Y 9 lesser angle so that when this lever is depressed the rod 87 is moved one step to the right (Fig. 6) or left (Figs. 18 and The slot 86 in the Received-onaccount" lever 1s cut atl a slightly greater angle, thereby moving the rod 87 one step farther than thev Cash key. By depression of either of these two keys, Cash or Received-on-account, the rod 87 is always maintained in the upper portion 264 of the slot 263, consequently' an operation of either of these twoA keys will have no elfect upon thelever 260.

However, the slot 86 in the Charge key is cut at a greater angle than either the Cash or Receivedfon-account keys, consequently when this key .is operated, the ro'd '87 is forced-into a porti 0n '265 of th'evslot 263, thereby rocking the lever 260 counterfclockwise (Fig.l 6) or clockwise (Figs. 18

and 22). This Vmovement of the lever 260 .through the pin 261 and slot 262 in thellinks 232 and 243 rocks said links clockwise (Fig.

6) o r counter-clockwise,(Figs. 18 and 22) by the Charge key. This also rocks the 1e- ',ver 260 clockwise (Figs. 18 and 22) which rocks the links 232 and 243 counter`-clock wisc with their upper ends as the pivot. The

upper portion of the slot 262 in each of the links 232 and 243 is shaped so that when either of said links is `moved downward to engage its respective totalizer, as previously described, said slot has no effect on the-pin 261 or lever 260. -When either the Charge7 or the Paid out key is depressed the pins 230 and 242 (Figs. 6, 18, 22 and 1B) are in such a position that when either of the levers 59 or 61 is rocked said pins will not strike the shoulder 238 or 248, but will move into a portion 266 of the openings 231 and 241. 'lhis portion 266 is deep enough to allow the full counter-clockwise (Fig. 6) or clockwise (Figs. 18` and 22) movement of either of the levers 59 and 61, consequently the links 232 and 243 are not moved downward, thereby preventing any movement of the levers 234 or 244, consequently neither of the totalizers are rocked into engagement with the actuating gears. The reason for having the slots in all four of the transaction key levers cut at difl'erent angles will be hereinafter explained in connection with the printing and indicating mechanism.

Transfer mechanism.

7 and 8). The tens, hundreds and thousands -totalizer Wheels 205 and 215 each have secured to the side thereof a pinion 297. Cooperating with the disk 295 and pinions 297 are three disks 293, provided with two pairs of teeth 299 and 300. The teeth 299 co-operate with the totalizer Wheels 205 and the teeth 300 co-operate with the totalizer wheels 215. These disks are Wide enough to be in the plane ot' the disks 295 and also in the plane of the pinions 297, consequently when the units of dollars Wheel passes from 9 to 0, this tooth 296 engages the teeth 299 or 300 as the case may be, and rocks the disk 298 counter-clockwise, which movement. is transmitted to the pinions 297, thereby causing the tensl of dollars wheel to be advanced one step. These disks 293 are each provided with a projecting arm 301 (Figs. and 3), `which co-operates with the previously described bail 287, so that when said bail is operated it restores these higher orc er transfer disks to normal position.

The disks 298 are each provided with .two V-shaped notches 302 and 303 (Fig. 8). Coo1 erating.
